• How to avoid code duplication for a system which has logic that may change year wise?

  - by aravind

  What would be the way to design a system which has logic that may change year wise? There is an application which conducts online exams. There are five questions for a particular subject. The questions may (or may not) change year wise. As per my current design, the questions in database are stored year wise. There are some year specific code logic as well. In order to enable the application for another year, the year specific database records and code will be copied or duplicated. How to avoid this code duplication?

• Ubuntu Server 13.04.3 doesn't boot w/ EFI

  - by user1004816

  I'm was actually trying to install Debian Wheezy (which failed horribly), then tried Ubuntu Server 13.04 and got the exact same problems as w/ Debian: After installing, the system doesn't show any boot-selection and tells me "Missing operating system". My setup is pretty simple: /dev/sdc - 1TB HDD (+ 3 other NTFS HDD) /dev/sdc1 - EFI, 100MiB, bootable /dev/sdc4 - ext4, 65GiB, Ubuntu/Debian (sdc2 & 3 are NTFS w/ data. Sorta lacking SATA-ports, therefore no OS-only HDD/SSD) Grub seems to be installed on /dev/sdc4, /dev/sdc1 only contains a "EFI"-folder. Not sure if thats correct. I used UNetbootin on OS X to make an 8GB USB-drive bootable and used the standard amd64-iso, running a perl-script wich eradicates a couple of naming-errors (different story). Using this tutorial and actually disabling UEFI and using legacy only dind't work either, the usb drive dind't even bother to boot. I'm pretty clueless here. I'd just like to install and use either Debian oder Ubuntu Server!

• I want to master ASP.NET - What concepts should I focus on/What concepts do you most value?

  - by Josh

  I start a job this summer doing work in ASP.NET 4 (C#). I plan on working with some legacy code as well as MVC. I want to get a running start. I have good understanding of HTML/CSS/Javascript, and pretty good understanding of C# itself, Design principles, Design Patterns, and understand masterpages, basic MVC2, and code behinds for web forms. In your opinion what aspects of ASP.NET are the most important to master for web applications? What do you value most in your usage of ASP.NET? Do you have a recommendation for understanding the internals of ASP.NET itself?

• Boot Ubuntu from a bootable USB hangs on purple screen

  - by user210946

  I recently bought a laptop (Lenovo Y410P) with Windows 8 pre-installed and I'm trying to dual boot Windows 8 and Ubuntu 13.0. I created a bootable usb using Pendrive. Then I changed the Boot Mode to Legacy Support and the boot order so it boots from the flash storage first. When I restarted the computer, I got the error message "SYSLINUX 4.06 EDD 2012-10-23 Copyright (c) 1994-2012 H. Peter Anvin et al" and it just hung there. Fair enough. After some googling I formatted my flash drive in FAT format instead of FAT32. The "SYSLINUX..." error message is gone but now it hangs on a purple screen http://imgur.com/WbdXpZN Does anyone have a suggestion what to do here? I've looked at various posts but none of them seems to have a solution that the author confirmed it worked.

• At what size of data does it become beneficial to move from SQL to NoSQL?

  - by wobbily_col

  As a relational database programmer (most of the time), I read articles about how relational databases don't scale, and NoSQL solutions such as MongoDB do. As most of the databases I have developed so far have been small to mid scale, I have never had a problem that hasn't been solved by some indexing, query optimization or schema redesign. What sort of size would I expect to see MySQL struggling with. How many rows? (I know this is going to depend on the application, and type of data stored. the one that got me thing was basically a genetics database, so would have one main table, with 3 or 4 lookup tables. The main table will contain amongst other things, a chromosome reference, and a position coordinate. It will likely get queried for a number of entries between two potions on a chromosome, to see what is stored there).

• 3D game editor with C++ support and Bullet Physics

  - by Raghav Bali

  I am very new to game development and hence the question. Is there any open-source game editor that uses Bullet Physics engine with C++ code edit support.I have read about blender but it allows python based editing(if I am not wrong here). I need an editor to quickly draw the needed objects and concentrate more on the logic on their interactions(mostly magnetism based). This(my project) is part of an already existing legacy code in C++ which is forcing the dependency. Also, is there any physics engine which provides support for magnetism? Any help will surely be great. Thanks

• Turnkey with LightSwitch

  - by Laila

  Microsoft has long wanted to find a replacement for Microsoft Access. The best attempt yet, which is due out in, or before, September is Visual Studio LightSwitch, with which it is said to be as 'easy as flipping a switch' to use Silverlight to create simple form-driven business applications. It is easy to get confused by the various initiatives from Microsoft. No, this isn't WebMatrix. There is no 'Razor', for this isn't meant for cute little ecommerce sites, but is designed to build simple database-applications of the card-box type. It is more clearly a .NET-based solution to the problem that every business seems to suffer from; the plethora of Access-based, and Excel-based 'private' and departmental database-applications. These are a nightmare for any IT department since they are often 'stealth' applications built by the business in the teeth of opposition from the IT Department zealots. As they are undocumented, it is scarily easy to bring a whole department into disarray by decommissioning a PC tucked under a desk somewhere. With LightSwitch, it is easy to re-write such applications in a standard, maintainable, way, using a SQL Server database, deployed somewhere reasonably safe such as Azure. Even Sharepoint or Windows Communication Foundation can be used as data sources. Oracle's ApEx has taken off remarkably well, and has shaken the perception that, for the business user, Oracle must remain a mystic force accessible only to the priests and acolytes. Microsoft, by comparison had only Access, which was first released in 1992, the year of the Madonna conical bustier. It looks just as dated. Microsoft badly needed an entirely new solution to the same business requirement that led to Access's and Foxpro's long-time popularity, but which had the same allure as ApEx. LightSwitch is sound in its ideas, and comfortingly conventional in its architecture. By giving an easy access to SQL Server databases, and providing a 'thumb and blanket' migration path to Access-heads, LightSwitch seems likely to offer a simple way of pulling more Microsoft users into the .NET community. If Microsoft puts its weight behind it, then it will give some glimmer of hope to the many Silverlight developers that Microsoft is capable of seeing through its .NET revolution.

• Fastest way to run a JSON server on my local machine

  - by Mohsen

  I am a front-end developer. For many experiemnets I do I need to have a server that talks JSON with my client side app. Normally that server is a simple server that response to my POSTs and GETs. For example I need to setup a server that saves, modifies and read data from a "library" database like this: POST /books create a book GET /book/:id gets a book and so on... What is the fastest and easiest technology stack for database and server in this case? I am open to use Ruby, Nodejs and anything that do the job fast and easy. Is there any framework (on any language) that do stuff like this for me?

• Part 8: How to name EBS Customizations

  - by volker.eckardt(at)oracle.com

  You might wonder why I am discussing this here. The reason is simple: nearly every project has a bit different naming conventions, which makes a the life always a bit complicated (for developers, but also setup responsible, and also for consultants).  Although we always create a document to describe the technical object naming conventions, I have rarely seen a dedicated document  with functional naming conventions. To be precisely, from my stand point, there should always be one global naming definition for an implementation! Let me discuss some related questions: What is the best convention for the customization reference? How to name database objects (tables, packages etc.)? How to name functional objects like Value Sets, Concurrent Programs, etc. How to separate customizations from standard objects best? What is the best convention for the customization reference? The customization reference is the key you use to reference your customization from other lists, from the project plan etc. Usually it is something like XXHU_CONV_22 (HU=customer abbreviation, CONV=Conversion object #22) or XXFA_DEPRN_RPT_02 (FA=Fixed Assets, DEPRN=Short object group, here depreciation, RPT=Report, 02=2nd report in this area) As this is just a reference (not an object name yet), I would prefer the second option. XX=Customization, FA=Main EBS Module linked (you may have sometimes more, but FA is the main) DEPRN_RPT=Short name to specify the customization 02=a unique number Important here is that the HU isn’t used, because XX is enough to mark a custom object, and the 3rd+4th char can be used by the EBS module short name. How to name database objects (tables, packages etc.)? I was leading different developer teams, and I know that one common way is it to take the Customization reference and add more chars behind to classify the object (like _V for view and _T1 for triggers etc.). The only concern I have with this approach is the reusability. If you name your view XXFA_DEPRN_RPT_02_V, no one will by choice reuse this nice view, as it seams to be specific for this CEMLI. My suggestion is rather to name the view XXFA_DEPRN_PERIODS_V and allow herewith reusability for other CEMLIs (although the view will be deployed primarily with CEMLI package XXFA_DEPRN_RPT_02). (check also one of the following Blogs where I will talk about deployment.) How to name Value Sets, Concurrent Programs, etc. For Value Sets I would go with the same convention as for database objects, starting with XX<Module> …. For Concurrent Programs the situation is a bit different. This “object” is seen and used by a lot of users, and they will search for. In many projects it is common to start again with the company short name, or with XX. My proposal would differ. If you have created your own report and you name it “XX: Invoice Report”, the user has to remember that this report does not start with “I”, it starts with X. Would you like typing an X if you are looking for an Invoice report? No, you wouldn’t! So my advise would be to name it:   “Invoice Report (XXAP)”. Still we know it is custom (because of the XXAP), but the end user will type the key “i” to get it (and will see similar reports starting also with “i”). I hope that the general schema behind has now become obvious. How to separate customizations from standard objects best? I would not have this section here if the naming would not play an important role. Unfortunately, we can not always link a custom application to our own object, therefore the naming is really important. In the file system structure we use our $XXyy_TOP, in JAVA_TOP it is perhaps also “xx” in front. But in the database itself? Although there are different concepts in place, still many implementations are using the standard “apps” approach, means custom objects are stored in the apps schema (which should not cause any trouble). Final advise: review the naming conventions regularly, once a month. You may have to add more! And, publish them! To summarize: Technical and functional customized objects should always follow a naming convention. This naming convention should be project wide, and only one place shall be used to maintain (like in a Wiki). If the name is for the end user, rather put a customization identifier at the end; if it is an internal name, start with XX…

• Google's process for publishing/modifying pages [closed]

  - by Glenn Dayton

  I'm assuming that a group of people at Google have control of certain sections of google.com, but how does Google make sure that employees don't accidentally or intentionally sabotage the website? Does Google use Adobe Contribute or some similar product for sharing/publishing the website. Do employees use WebDAV, FTP, SFTP, or SSH to publish the site. Since Google has hundreds of thousands of servers it probably takes some time for its servers to update. Do they transmit the new copy of the website to all servers before publishing at once? This question does not apply to Google editing a database and having a page reflect the database's changes. It applies to employees editing the source code and/ or back end of the site.

• Questions about identifying the components in MVC

  - by luiscubal

  I'm currently developing an client-server application in node.js, Express, mustache and MySQL. However, I believe this question should be mostly language and framework agnostic. This is the first time I'm doing a real MVC application and I'm having trouble deciding exactly what means each component. (I've done web applications that could perhaps be called MVC before, but I wouldn't confidently refer to them as such) I have a server.js that ties the whole application together. It does initialization of all other components (including the database connection, and what I think are the "models" and the "views"), receiving HTTP requests and deciding which "views" to use. Does this mean that my server.js file is the controller? Or am I mixing code that doesn't belong there? What components should I break the server.js file into? Some examples of code that's in the server.js file: var connection = mysql.createConnection({ host : 'localhost', user : 'root', password : 'sqlrevenge', database : 'blog' }); //... app.get("/login", function (req, res) { //Function handles a GET request for login forms if (process.env.NODE_ENV == 'DEVELOPMENT') { mu.clearCache(); } session.session_from_request(connection, req, function (err, session) { if (err) { console.log('index.js session error', err); session = null; } login_view.html(res, user_model, post_model, session, mu); //I named my view functions "html" for the case I might want to add other output types (such as a JSON API), or should I opt for completely separate views then? }); }); I have another file that belongs named session.js. It receives a cookies object, reads the stored data to decide if it's a valid user session or not. It also includes a function named login that does change the value of cookies. First, I thought it would be part of the controller, since it kind of dealt with user input and supplied data to the models. Then, I thought that maybe it was a model since it dealt with the application data/database and the data it supplies is used by views. Now, I'm even wondering if it could be considered a View, since it outputs data (cookies are part of HTTP headers, which are output)

• How to write functionally in a web framework

  - by Kevin Burke

  I love Rich Hickey, Clojure and Haskell and I get it when he talks about functions and the unreliability of side-effecting code. However I work in an environment where nearly all the functions I write have to read from the database, write to the database, make HTTP requests, decrement a user's balance, modify a frontend HTML component based on a click action, return different results based on the URI or the POST body. We also use PHP for the frontend, which is littered with functions like parse_str(), which modifies an object in place. All of these are side-effecting to one degree or another. Given these constraints and the side-effecting nature of the logic I'm coding, what can I do to make my code more reliable and function-able?
